There is a consumer who works in a home appliance store. Every time there is a power outage, he receives 5-10 calls a day about burnt-out control panels. So, is there a surge protector to protect home appliances, such as expensive refrigerators? This article gives my thoughts on this issue. If you find it useful, please give me a thumbs up.
Why do power outages occur?
(1) Planned maintenance and power outages:
After a certain period of operation, power equipment must be shut down for maintenance to ensure its normal operation.
Some lines may also need to be shut down to cooperate with urban construction or power grid transformation.
New customer connection construction or power grid equipment capacity expansion, line transformation, etc. will also be scheduled for power outages.
(2) Power grid load adjustment to avoid peak power rationing:
When there is an imbalance between power generation, power supply, and power consumption, and the power grid is overloaded, to ensure the safety of the power grid, power rationing measures will be taken, resulting in power outages on some lines.
(3) Power outage due to power equipment failure:
In any link of power generation, transmission, transformation, distribution, and consumption, equipment failure may cause a power outage.
Residents may privately add electrical equipment, use it beyond capacity, or the lines are outdated, the joints are oxidized, etc., which may also cause power outages.
Natural disasters such as storms, fires, earthquakes, etc. may also damage power plants and power supply facilities, causing power outages.
(4) Temporary power outage:
If it is found that the equipment has major hidden dangers, it is necessary to arrange a power outage for maintenance immediately.
In order to cooperate with other units’ construction projects, such as demolition and road construction, temporary power outages may be required.
In order to ensure the safety of the power grid and construction personnel, or to avoid certain risks (such as forest fires), some power lines may also be temporarily shut down.
During a power outage, the voltage protector can protect household appliances from damage.
The function of the AVP automatic voltage protector:
The automatic voltage protector is an electronic product that can detect changes in the voltage of a household power supply. Once an abnormal change in voltage is detected, such as excessive voltage, too low voltage, or fluctuation, it will immediately separate the electrical facilities from the power grid, thereby protecting the electrical appliances from voltage damage.
Relationship between a power outage and voltage fluctuation:
After a power outage, when the power is restored, the voltage in the power grid may be unstable or momentary overvoltage. These power problems may cause damage to household appliances.
Especially in some areas, if the power problem is serious and voltage fluctuations or power outages often occur, it is particularly necessary to install a voltage protector.
The specific role of voltage protector in a power outage:
During the process of power restoration after a power outage, the voltage protector can quickly respond to voltage changes, cut off the circuit in time, and prevent electrical appliances from being damaged by overvoltage.
It can also absorb the energy released during overvoltage and convert it into heat or other forms, thereby reducing the impact on the equipment and extending the service life of the equipment.
Differences between air switches and leakage protectors:
Air switches mainly protect electrical equipment from damage when the current is too large or the live and neutral lines are short-circuited, while leakage protectors are designed to prevent electric shock accidents. However, these two types of protectors will not trip when the voltage is too high or too low, so they cannot completely protect electrical appliances from the threat of voltage damage.
In contrast, voltage protectors can automatically cut off power when the voltage is abnormal, providing comprehensive protection for electrical appliances.
In summary, it is very necessary to install a voltage protector during a power outage, which can ensure that household appliances are protected from the threat of voltage damage when the power is restored.
What measures can be taken to deal with power outages?
When encountering a power outage, you can take the following measures to deal with it:
(1) Check the electricity bill and switch
First, confirm whether the power outage is caused by arrears in electricity bills. You can check the balance of the electricity bill account.
Check whether the switch or circuit breaker at home has tripped. If it has tripped, try to push it up to restore power.
(2) Report and contact
If there is no abnormality in the internal inspection, it may be an external power outage. You should call the power department’s service hotline in time to report the power outage and wait for professional personnel to handle it.
Users living in apartments or communities can also contact property management personnel for help.
(3) Use emergency lighting
When there is a power outage, emergency lighting tools such as flashlights and candles should be used, but be especially careful when using candles to avoid fire risks.
(4) Backup power and equipment protection
You can prepare a backup power supply at home, such as a UPS uninterruptible power supply or a small backup power supply, to ensure the normal operation of important equipment such as computers and mobile phones.
For equipment that needs to keep working, a backup power supply is a small artifact in living alone, which can ensure that the equipment can continue to work during a power outage.
(5) Safety precautions
If there is a burning smell, smoke, or discharge in the home, all power should be cut off immediately to prevent fire.
When using a generator, ensure good ventilation to avoid carbon monoxide poisoning, and regularly check the fuel and oil conditions of the generator to avoid overloading.
